The first element is disputed, but is likely from ǫ́ss, áss (“god; one of the Æsir”), from Proto-Germanic *ansuz. Another theory is that it comes from áss (“hill, beam”), from Proto-Germanic *ansaz, but… Root origin matters for spelling because borrowed morphemes (Greek, Latin, Old French, Old English) carry their source-language orthographic conventions into modern English, which is why historical etymology is often the cleanest predictor of whether a cluster like "-ough", "-eau", or "-tion" will appear.
